WaveBench v0.4.0 - arbitrary waveform closure / 任意波形闭环

WaveBench v0.4.0 closes the first real arbitrary-waveform loop for the RIGOL DG4202 and R&S RTM2032 lab pair.

WaveBench v0.4.0 为 RIGOL DG4202 与 R&S RTM2032 这套实验仪器组合打通了第一条真实的任意波形闭环。

The scope of this release is deliberately small: take a CSV/NPY waveform, validate and map it into DG4000/DG4202 14-bit DAC data, upload it through DATA:DAC VOLATILE, capture the result with RTM2032, and preserve enough evidence to decide whether the loop actually worked.

本次发布的范围刻意收窄：读取 CSV/NPY 波形，校验并映射为 DG4000/DG4202 14-bit DAC 数据，通过 DATA:DAC VOLATILE 上传，用 RTM2032 采集结果，并保留足够证据来判断这条回路是否真正跑通了。

Highlights / 亮点

  • Added DG4202 arbitrary waveform upload through DATA:DAC VOLATILE.
  • 新增 DG4202 任意波形上传功能，通过 DATA:DAC VOLATILE 实现。
  • Added raw byte transport support with InstrumentTransport.write_bytes() and PyVISA write_raw.
  • 新增原始字节传输支持，通过 InstrumentTransport.write_bytes() 和 PyVISA write_raw 实现。
  • Added DG4000/DG4202 14-bit DAC binary block generation from validated CSV / NPY waveforms.
  • 新增从校验后的 CSV / NPY 波形生成 DG4000/DG4202 14-bit DAC 二进制块的功能。
  • Promoted source arb-load from dry-run-only payload validation to a minimal upload command.
  • 将 source arb-load 从仅 dry-run 的负载校验提升为可实际上传的最小命令。
  • Added source.arb_load run-plan step so upload, output enablement, capture, and [steps.expect] checks can live in one explicit plan.
  • 新增 source.arb_load run-plan 步骤，使上传、输出使能、采集和 [steps.expect] 检查能共存于一个显式计划中。
  • Recorded the first real closure evidence: DG4202 triangle arbitrary waveform -> RTM2032 capture -> FFT peak at 1 kHz -> static report.
  • 记录了首条真实闭环证据：DG4202 三角任意波形 → RTM2032 采集 → 1 kHz FFT 峰值 → 静态报告。

CLI example / 命令行示例

Dry-run validation remains available:

Dry-run 校验仍然可用：

python -m wavebench source arb-load \
  --channel 1 \
  --file waveform.npy \
  --name REI_ARB \
  --amplitude 1.0 \
  --offset 0.0 \
  --export-payload data/arb/REI_ARB.json \
  --dry-run

Upload requires an explicit playback frequency:

上传需指定回放频率：

python -m wavebench source arb-load \
  --config wavebench.toml \
  --channel 1 \
  --file waveform.npy \
  --name REI_TRI \
  --amplitude 1.0 \
  --frequency 1000 \
  --offset 0.0 \
  --output-on

Run-plan example / Run-plan 示例

[[steps]]
kind = "source.arb_load"
channel = 1
file = "data/arb/triangle_1024.npy"
frequency_hz = 1000
amplitude_vpp = 1.0
offset_v = 0.0
output_on = true

[[steps]]
kind = "scope.capture"
channel = 1
label = "arb_triangle_1k"
window_frequency_hz = 1000
target_cycles = 10
target_vpp = 1.0
screenshot = true

[steps.expect]
voltage_vpp_v = { min = 0.8, max = 1.2 }
frequency_estimate_hz = { min = 950, max = 1050 }

Validation / 验证

  • python -m pytest -q -> 150 passed
  • git diff --check -> OK
  • Lab closure record / 实验室闭环记录: doc/project/WaveBench_v0.4_闭环验证记录.md

Not included / 未包含

v0.4.0 is not an arbitrary-waveform editor. It does not add GUI editing, cross-vendor waveform abstraction, non-volatile waveform library management, RAF / Ultra Station workflows, or automatic waveform synthesis.

v0.4.0 不是一个任意波形编辑器。它不包含 GUI 编辑、跨厂商波形抽象、非易失波形库管理、RAF / Ultra Station 工作流，也不包含自动波形合成。

Those can come later. This release is about proving the first small loop.

这些可以以后再做。本次发布的意义在于证明第一条小回路是可行的。
